REPLACE BATTERY
The UPS automatically tests the battery’s condition and will illuminate the replace battery
LED and emit a short beep. This tone will be repeated every hour until the battery passes a
self test. It is recommended that the UPS be allowed to charge overnight before performing
a battery test to confirm a replace battery condition.
LOW BATTERY WARNING
The UPS will emit a steady tone when the battery reserve runs low. It continues to emit the
steady tone until AC returns or the UPS shuts down from battery exhaustion.
